Powerscourt Estate (Irish: Eastát Chúirt an Phaoraigh), located in Enniskerry, County Wicklow, Ireland, is a large country estate which is noted for its house and landscaped gardens, today occupying 19 hectares (47 acres). The house, originally a 13th-century castle, was extensively altered during the 18th century by German architect Richard Cassels, starting in 1731 and finishing in 1741.[1] A fire in 1974 left the house lying as a shell until it was renovated in 1996.

Foreword, the Wingfields had long coveted the lands of Phelim McCartan of Powerscourt (sl.1603), seeking to draw Phelim McCartan into an act of rebellion, the penalty for which was forfeiture. The feud climaxed on the 14 May 1603 when the Wingfields murdered Phelim in the place known as the Killing Hollow near Powerscourt, despite the fact that Phelim's grandson and heir Turlough son of Phelim's son (d.1616) remained in occupation of Powerscourt. King James I of England (d.1625) on 27 October 1603 granted a lease of the manor of Powerscourt for 21 years to Sir Richard Wingfield for a rent of £6 Irish and a knight's fee. The reasons for the forfeiture of the McCartan estates were because of the rebellious acts of Brian O'Neill (d.1549) and Phelim McCartan himself. That the actions of O'Brien, O'Neill & McCartan, Lord of Kinelarty, were cited as a reason for forfeiture was bizarre given the fact that at least Phelim McCartan received a posthumous pardon for unspecified offences on 23 April 1549. Furthermore, alongside Baron Cromwell his estates were surrendered to regrant.

The original owner of the 13th-century castle was a man by the name of La Poer, which was eventually anglicised to "Power." The castle's position was of strategic military importance because the castle's owner could control access to the nearby Dargle, Glencree and Glencullen rivers.

The three-story house had at least 68 rooms. The entrance hall, where family heirlooms were displayed, was 18 metres (60 ft) long and 12 metres (40 ft) wide. The main reception rooms were on the first floor rather than on the ground floor, the more typical location. A mile-long avenue of beech trees leads to the house.

During the 16th century the house came into the ownership of the Powerscourt family. The family rose in wealth and prominence, and in the 18th century Richard Wingfield, 1st Viscount Powerscourt, commissioned the architect Richard Cassels to extensively alter and remodel the medieval castle to create a modern country house. Work started in 1731 and finished in 1741.

On a commanding hilltop position, Cassels deviated slightly from his usual sombre style, giving the house something of what Sir John Vanbrugh would have called the 'castle air.' This is most noticeable in the structure's severe palladian facade bookended by two circular domed towers.

In 1844, at the age of 8, Mervyn Wingfield, 7th Viscount Powerscourt, inherited the title and the Powerscourt Estate, which comprised 200 km² (49,000 acres) of land in Ireland. When young Lord Powerscourt reached the age of 21, he embarked on an extensive renovation of the house and created the new gardens.

Main attractions on the grounds include the Tower Valley (with stone tower), Japanese gardens, winged horse statues, Triton Lake, pet cemetery, Dolphin Pond, walled gardens, Bamberg Gate and the Italian Garden. The Pepperpot Tower is said to be designed after a favoured 3-inch pepperpot of Lady Wingfield. Of particular note is the Pets Cemetery, whose tombstones have been described as "astonishingly personal".[citation needed]

In 1961, the estate was sold by The 9th Viscount Powerscourt to the Slazenger family, who still own it to this day. Wendy Slazenger, daughter of the late Ralph Slazenger, married The Hon. Mervyn Wingfield (1935-2015) in 1962. Mervyn later succeeded, in 1973, as The 10th Viscount Powerscourt. Through her children, the 11th Viscount - Mervyn Anthony Wingfield - and the Hon. Julia Wingfield, there remains a strong connection between the two families and the Powerscourt Estate.

The house was destroyed by fire on 4 November 1974 and was subsequently renovated in 1996. Only two rooms are open to the public as they once appeared while Powerscourt had residents, while the rest of ground floor and first floor are now retail units.

In 2011, the Lonely Planet voted Powerscourt in the Top Ten Houses in the World while in 2014, National Geographic listed Powerscourt as No. 3 in the World's Top Ten Gardens.

Powerscourt Waterfall and its surrounding valley are also owned by the Powerscourt Estate, although the two pieces of land are no longer directly connected. At 121 metres (397 ft), it is the highest waterfall in Ireland. In 1858, The 7th Viscount Powerscourt established a deer park around the waterfall, resulting in the successful introduction of the Japanese Sika to Ireland.

Regular bus service from Powerscourt to the waterfall was discontinued in 2005, though during the high summer season, intermittent bus services are still available. The waterfall is seven kilometres from Enniskerry, and walkable. While the distance is not prohibitive, walking can be dangerous, as the road is narrow, and lacks a shoulder for long stretches.

A separate entrance fee is required for access to the waterfall, ranging from €3.50 (children) to €6 (adults).[4]

Powerscourt Golf Club, located at the Powerscourt Estate in County Wicklow, Ireland, is home to two par 72, 18-hole courses: the East, which was created first, and the West. Both contain fast greens and hilly fairways, and they are each over 6,900 yards (6,300 m) long. In 1998, the East Course was host to the Irish PGA Championship.[5][6]

Powerscourt House is the ancestral home of the fictional Lord Francis Powerscourt in David Dickinson's series of novels about the Victorian detective (Goodnight Sweet Prince, Death And The Jubilee, Death Called To The Bar).[citation needed]

The Hallmark Channel original film "Honeymoon for One", starring Nicollette Sheridan was filmed at the estate using external scenes of the house and the waterfall.[8] The film's plot included a fight between the owners of "Castlewilde" (Powerscourt) and local citizens concerned about the building of a golf course, which the real estate has.[9]
